In the life of every woman without significant health issues, a menstrual cycle (period) occurs within an average span of 28 days, typically ranging from 21 to 35 days.

This period, lasting roughly between 2 to 7 days, is largely regulated by hormonal balance in the body. Variations outside this cycle, exceeding by at least 7 days, are referred to as menstrual delay. Multiple factors can disrupt this cycle, causing delays.

Studies show that nearly all women experience irregular periods at some point. Encountering such delay more than 2 or 3 times a year can indicate serious health issues.

While 2-3 instances of irregularity per year are considered normal, more than 3 occurrences warrant a visit to the doctor for examination. This narrative differs for individuals experiencing their first period; irregularities during this time are quite common until the cycle stabilizes.

Numerous minor factors, such as environmental triggers, stress, psychological factors, seasonal transitions, hormonal shifts, or various medications, can lead to menstrual delay.

If a woman becomes pregnant, her menstrual bleeding stops. The cessation of bleeding for 7 days or longer is defined as a menstrual delay.

Reasons for menstrual delay are varied. Top known causes include:

1. Pregnancy: Common cause of menstrual delay, especially in sexually active women not using protection.
2. Intense Exercise Programs: Increasing exercise without adjusting calorie intake can cause menstrual delay.
3. Chronic Diseases: Long-term or lifelong chronic diseases directly impact menstrual regularity.
4. Polycystic Ovary Syndrome (PCOS): Overproduction of male hormones by ovarian cysts can lead to delays.
5. Weight Loss or Gain: Body changes can negatively impact ovulation and disrupt menstrual cycle.
6. Nursing, Postpartum Period: Delays can occur during nursing and the postpartum period.
7. Birth Control Pills: Regular users often face irregularity, which can take up to 6 months to normalize after stopping.
8. Stress: Stress can affect the hypothalamus in the brain, disrupting the menstrual cycle.
9. Thyroid Disorders: Hyperthyroidism or Hypothyroidism can cause menstrual delays.
10. Early Menopause: Menopause typically occurs between 45-55. Earlier onsets can decrease the number of eggs and disrupt menstrual cycle.

Symptoms of menstrual delay include severe abdominal and back pain, potential for pregnancy, positive home pregnancy test, missing two regular periods without knowing the cause, and not having a period by age 16 or not having breast development or pubic hair by age 14.

If you're experiencing menstrual delay, don't hesitate to consult your doctor for health checks. Remember, understanding menstrual delay is the first step towards managing it effectively.
